Slave to a Fat Ass
by Gambit165

PART 1

After leaving work late one night, I heard footsteps coming towards me as I was about to unlock the car. Before I could turn to face the sound, there was a sharp pain in my head and I fell to the ground. As I faded out, I could see a pair of legs come into view.

I awoke with a start, but found myself unable to move. Leather restraints had been attached to my wrists, upper arms, chest, ankles, and just above the knees. There also seemed to be some kind of brace around my neck preventing me from looking around, and this was also strapped to the bed. The restraints did their job preventing much movement from the poor, helpless person caught in them.
"MMMMGGGGGHHHFFFFF!!!" I tried to shout for help, only to realize I had been gagged with some kind of dirty cloth. Tape had also been wound tightly around my head. What really worried me right then, was the taste of the cloth. I wasn't sure what it was, only that it was very unpleasant.

After I had been left to struggle for a while, the door finally opened. I couldn't turn to see who was coming in, but could hear footsteps.
"Looks like my new toy is awake." A mystery woman said near the door.

The woman walked over, and I got a good look at my captor. She looked fairly young, and would be attractive, if not for how fat she was. She had to weigh at least 400 lbs, and she smelled very ripe. It was almost like she didn't shower much, if at all.

"Just so you know, we are away from civilization so nobody can hear you and nobody is coming to save you" The woman said, gently caressing the side of your tape-gagged face.
"In fact, I didn't even need to gag you. I just did it for fun!"

I tried to plead with her, the words getting garbled and muffled, and the girl just laughed.
"I love the sounds that gagged boys make, especially when they find out what I have in store for them."

The girl turned around, giving me an up-close view of her massive ass barely contained by a skirt. As she lifted up the skirt, I could see she wasn't wearing panties.
"If you're wondering what's in your mouth, it's the thong I was wearing all day today."
I screamed into the panties taped in my mouth and tried to struggle. I had to break free and get this disgusting fat bitch's panties out of my mouth. My struggles were in vain.

"I hope you're ready to be my chair."

Helpless to do anything about it, I watched the big fleshy ass come down onto my face. My entire face was wedged in the sweaty crack of the fat girl. As you can imagine, it's very hard to breath with your mouth taped and your nose buried in a big fat ass. After about 30 seconds, she lifted one cheek off my face, giving me room to breath. Unfortunately, all that did was force me to sniff her ass crack desperately. I almost threw up, just barely managing to keep it down. The cheek came crashing back down, once again trapping me in the damp, smelly cave that was her ass. This cycle of suffocation, ass sniffing, and further suffocation continued for a very long time. Eventually, the girl leaned forward to lay her head on my stomach. This freed my nose from its fleshy prison, but the ass was still on my face. I could breath, but to do so I had to keep sniffing that ass.

Suddenly, I heard a rumble coming from her stomach. "Uh oh! I think I have to fart, but I really don't want to move" the girl said. "Can I just fart in your face?"
I tried to scream "No!", but the tape and panties kept me well gagged.
"Thank you, I really didn't want to get up." She said, and started to push.

My face was assaulted by a disgusting fart, followed by two smaller ones right after. I got each one full blast, right up my nose. I coughed and gagged, and tried to blow the fart out, but I had to lay there and suffer the smell as long as she wanted me to. Another fart was released, and I was right on the verge of either throwing up or passing out. She never seemed to run out of gas, as each one came just seconds after the one before it. This was inhuman, and the smell was beastly. I actually started to cry.

Eventually, I passed out, unable to take the stink and the weight any longer. I woke up, no longer tied up in the strange room. I was actually in my car with the keys in the ignition.
"That was a fucked up dream, what the hell is wrong with me?" I asked. As I got ready to start the car, I saw an envelope taped to the dashboard. Hesitating for a moment, I finally opened it. Inside was a note, and a couple of pictures. The note read:

'I hope you had fun, I know I did! I just love making defenseless boys sniff my butt, among other things. I could have kept you tied up, but I had something better in mind. Let's just say, I own a part of you now. You'll see what I mean soon enough. I left my email at the bottom of the page when you cant take it anymore and come crawling back to me. See you soon!
love, your secret admirer. '

I took a look at the pictures. Most of them were of me, face stuck up her big fat ass. The last one was much more worrying. It was of my dick, being locked into some kind of device. I unzipped my pants and pulled it out. Sure enough, there was a metal piece covering my dick, like some kind of chastity device. I couldn't remove it, and jerking off was going to be impossible with this thing on. This thing was pretty sophisticated, a keyhole near the top was built directly into the cage, so there wasn't even a padlock I could cut off. Only a key was going to open this.

"Fuck." I said out loud, wondering how long I could hold out before contacting her.

PART 2

Two weeks ago, I was abducted by some woman I had never met. I woke up in an undisclosed location, and spent quite a while being tormented by the fat smelly ass of my captor. I was eventually "freed" by her, but there was a major catch. Ever since that day, I have been locked into a sophisticated Chastity Belt. Two weeks, I have dealt with the frustration of unfulfilled sexual desires. Many attempts have been made to either remove the belt, or at least try to get some stimulation with it on. I quickly found out both of those goals were impossible. The feeling of my dick straining against the metal enclosure is driving me insane. Each time I see an attractive woman, I am painfully reminded that I am still very much a prisoner. All things considered, I think lasting two weeks without breaking is admirable. Unfortunately, every person has a breaking point.

While looking at the pictures of her giant ass smothering my face, illustrating both a traumatizing past and a rapidly approaching future, I sent an email to the address she gave me. The Email read: 'My name is Charles, I'm the man you kidnapped a couple of weeks ago. What exactly would it take to get this damn thing off my dick?'

I waited by the computer, trying to ignore the frustrating feeling in my crotch. My body wasn't able to ignore it however, as I couldn't stop humping air like a dog that hasn't been fixed. It didn't take long for a reply to come, surprisingly. I opened the email and read.

'It's simple, Charles. You become my property, submit to me completely, and I will allow your poor restricted dick to see freedom. Under my terms of course. While you are with me, the cage comes off. While you are away from me, the cage goes back on. I will have total control, and will be able to do whatever I want to my property. I promise not to hurt you, other than feeling my weight on your body whenever I feel like sitting on you. If you agree to these terms, just send another email simply saying "Yes Mistress" and I will be at your house soon after.'

I finished reading, sighing heavily. There wasn't going to be a good way out of this, I just hoped I could survive what was to come. I send the reply email, and went to go wait in the living room. After about half an hour, I heard knocking and went to answer the door. There she was, my own personal Satan in the body of a young, obese woman. She had a black bag on her shoulder, big enough to hold lots of things that I probably didn't want to deal with.
"Well hello there, my pet!" she said in a cheerful tone.
"Um, hello." I said awkwardly.
The girl frowned. "I'm going to let that one slide, but in the future you will always call me Mistress, or Miss Katie if you prefer."
"Alright...Mistress."

Miss Katie had me show her around my small house, and eventually we got to my bedroom. Once I opened the door, Miss Katie shoved me inside and closed the door behind her. She unzipped the bag and ordered me to come over to her. She also ordered me to strip completely nude, except for the Chastity Belt obviously. Reluctantly, I did as instructed, and she pulled a big roll of duct tape from the bag. Miss Katie proceeded to bind me in the tape. She wrapped my torso, pinning my arms to the sides. She then wrapped my forearms to my hips, and even taped my fingers together so I couldn't mess with the tape in any way. The same was done to my lower body, tape wrapping my ankles, calves, and thighs together. I had become a Mummy of sorts, only with most of my body still exposed.

Katie took a step back to admire her handywork, while I struggled not to fall over.
"It's nice, but it's missing something." Katie said. She slowly took off her pants, showing me a pair of purple cotton panties. She turned around, and I could see most of the back was currently wedged between her thick ass cheeks. I could even see sweat stains, and dreaded what she might have in mind. My fears were confirmed as she peeled the panties out of her crack and took them off as well. The panties were balled up, and brought to my mouth, which stayed closed.
"You aren't allowed to disobey me, remember? I own your dick, and by extension I own you." Katie said, using a domineering tone she hadn't used up to this point. "Right now I want to put my sweaty panties in your mouth, and tape it shut. You are in no position to resist, so just open up."

I whimper a little, knowing I didn't really have a choice. I slowly opened my mouth, and it was promptly filled to the brim with foul-smelling, damp cotton. The sheer size of the panties caused my cheeks to bulge out. The sound of tape ripping off the roll came soon after, and multiple layers of tape went around my head to trap the panties and effectively shut me up. I was then picked up and placed on my bed. Miss Katie climbed onto the bed, placing one leg on either side of my head. I stared into the abyss that was her deep, smelly ass crack. The mass of butt-flesh lowered onto my face, trapping me in a dank prison. My senses were assaulted by B.O and the smell of stale farts. Her ass and my head both sank into the mattress and I once again became a chair for this sadistic woman.

Once she had gotten settled on my face, Miss Katie did as she promised. I could feel a key enter the lock, and my little friend was finally free. Despite how disgusting the smell, her ass on my face was beginning to have an effect on my dick. I guess after a few weeks of not being able to get hard, almost anything can set it off. I felt a hand reach out and grasp my dick. She played with the head, causing me to jump and to cry out with muffled moans. She expertly teased my dick, getting me ever closer to the edge without letting me Cum. She was also keeping me in a constant state of suffocation, only allowing me small breaths between smothering. Her hips were gyrating as I could feel her pussy grinding on my chin. Her movements became quicker and more forceful as she built up to a massive climax. All at once she nearly screamed as she came, and I could feel her juices run off my duct tape gag and start to run down my neck.
"Oh, fuck yes!" she said, breathlessly.

Miss Katie leaned forward, laying her head next to my dick. This gave me more room to breath, and I started to desperately inhale the ungodly smell of her ass. As I did, I heard a *BRRRAAAAPPPPP* as a wet fart hit me directly in the face.
"MMMMMMGGGGGGGHHHHHHHH!!!!" I screamed into the panties and tape, Miss Katie just responded with another fart up my nose. As she was Gassing me out, she also started playing with my dick at the same time. It felt amazing, in direct contrast to the rotten shit smell I was forced to endure. I was beyond thinking at this point. The stench was unbearable, but my dick was still rock hard. This woman was an expert in keeping men on the edge of orgasm, and she spent the better part of three hours teasing my dick mercilessly while I helplessly smelled her ass and farts. She stroked, licked, tickled, sucked, and massaged, pulling back just before I could get the relief I needed. Each time I got close to the edge, she would fart in my face. To my surprise, and horror, I was starting to get used to the smell.

I began begging incoherently through my gag, desperate to cum after hours of torment. Miss Katie decided to give me a chance. She got off my face, turned around, and started to undo my gag. The tape came off, as did some hair behind my head, and she pulled the panties out of my mouth. Despite being able to speak now, I instead could only pant and try to form words unsuccessfully.
"I will let you Cum, but there is something else you have to do first."
She sat her fat ass back on my face.
"Now kiss this glorious ass, and thank me for the privilege."

Without hesitation, I got to work kissing the ample backside of my new owner. After each kiss, I mindlessly said "Thank you, Mistress."
She didn't let me stop until she felt my lips touch every inch of both ass cheeks. She told me to stop, and then spread her ass cheeks apart.
"Now stick out your tongue, and keep it out."
I stuck my tongue out, and she sat her full weight back on my helpless face. My tongue found its way directly into her asshole, forcing me to taste leftover shit from her last trip to the bathroom. Now that my tongue had become her butt-plug, she started stroking my dick once again. This time, unlike the previous three hours, she wasn't going to stop until I reached climax. My senses were being overwhelmed by smell, taste, crushing weight, and intense sexual pleasure. I was running out of air, but I was more focused on the feeling in my cock. I could feel myself getting faint, but just before I was about to pass out I came explosively. Two weeks of buildup shot out, covering my thighs and stomach in sticky white cum. The ass was pulled off my face, my tongue leaving the asshole with a wet popping sound. I lay there, panting and completely exhausted, as Miss Katie left the room. She soon came back with a wet towel and started cleaning my face, and the spots where my jizz landed.

After making sure I was cleaned up, she left once again and came back with food. She kept me tied up, deciding instead to feed me herself.
She looked over at the clock, saying "Wow, it's pretty late. I think we should just go to sleep, don't you think my Pet?"
I didn't say anything, I just nodded. Miss Katie got into bed, wrapping her arms around my bound body. As she cuddled her property, we both drifted off to sleep. This would be the start of my new life, one that I actually grew to love as time went on, thanks mostly to the sexual conditioning I had to endure during the early part of my newfound slavery.

PART 3: What Dreams May (Not) Cum

Ever since that fateful night where I officially became Miss Katie's property, my morning routine has changed. I still do the usual: brush my teeth, take a shower, and get ready for work. Only now, I have to try ignoring the uncomfortable pressure and unfulfilled sexual desire from my caged dick. Miss Katie, of course, does everything she can to make it impossible to ignore.

My phone blinked with a notification. My daily morning text message from Mistress was waiting for me.

'Good morning, my Pet. How are you feeling?'

I read the message, and opened the enclosed picture. The sight of my Mistress, showing off her new lace panties which hugged her ample backside and showed off every curve, added to my growing frustration. It had been almost a week since she allowed me to cum while using me as a chair. Since then, I'd received daily pictures to remind me of exactly who owned me now.

'Frustrated as usual, Mistress. I often dream of being back between your beautiful cheeks'

I finished getting ready for work while waiting for a response. It's true, my dreams are often about the ass of Miss Katie. The last couple of days, the dreams have been much more vivid. I can feel her weight pinning me to the bed. I can taste her ass sweat dripping into my mouth. I can smell each fart being forced up my nose, causing me to gag on the stench. I still don't particularly enjoy the smell or the taste, but my poor imprisoned dick reacted anyway.

Just before leaving my house, I got the response I had been waiting for.

'Glad to hear it. I love the thought of you squirming helplessly, desperate for release, while you think about being in your rightful place. You belong under me, fighting for air as I use your face to get off'

My knees went weak reading those words. Today was going to be a rough one. Suddenly, another message came through.

'I want to take you out on a proper date tomorrow, I know you're free then. I have some fun ideas. Hope you're ready.'

-That night-

I could barely sleep. A mixture of worry and excitement flooded my emotions as I thought of what Miss Katie had in store for me. After some time, I did manage to drift off. As usual, my dream self was bound head to foot. I spent the whole night kissing her cheeks and giving her asshole a thorough tongue bath. Mistress was very gassy, each rank fart pushing its way over my tongue and filling my mouth. Some were so forceful, I got to experience the odd sensation of a fart coming out of my nose instead of going in, singeing my nose hairs with a powerful methane stench. This continued for some time as Mistress used my face to grind out orgasm after orgasm, never allowing me the same pleasure. I was mindless with lust, muffled moans barely audible while I was stuck in her ass.

"We're going to have so much fun tomorrow" Miss Katie said as she tormented my subconscious. "Time for you to wake up and prepare for what's in store"

My eyes opened, Miss Katie no longer there. My hand instinctively went to my cock and was once again met with the restrictive chastity. I sighed, took a cold shower, and waited for my Mistress.

Today she was going to take things to a whole other level, I just wish she told me what to expect so I could mentally prepare. Instead, I just tried to accept the fact that she owned me, and I had to be obedient no matter what she had in store. When the newest message arrived, my heart fluttered and I opened it immediately.

'Be ready, Pet. I'll pick you up in 20 min. This will be so much fun...for me'

The fear I experienced was strong, but not quite as strong as the desperate need to cum. There was something else, however. Something buried inside the frustration.

I had a very powerful desire to do everything I could to please Mistress. Today, I would get a chance to fulfil that need.
